INTRODUCTION
An Operator's manual, Service manual and a Parts catalog are provided by Tigercat to assist the dealer,
customer and operator in becoming familiar with the features of the 620C Skidder serial numbers
6200501 TO 6205000.
The operator's manual will assist the operator with the techniques of proper and safe operation of the
Skidder. The service manual contains safety guidelines, a preventive maintenance schedule and
servicing procedures to ensure optimum machine performance.
Section 1 in both the operator's manual and the service manual contains safety information that must be
followed. As well, throughout the rest of the manuals WARNING and CAUTION notices are displayed
where necessary, drawing attention to possible hazards when performing certain procedures.
Only trained personnel should be allowed to operate or work on the machine.
The information contained in this manual is current at time of printing. Improvements to the machine are
on-going and may not be covered, therefore in these cases contact your Tigercat dealer for the
appropriate information.
The phrase "and up" appearing in this manual after the serial number implies that the related
information is current for any machine serial number HIGHER than the serial number preceding the "and
up".
Tigercat reserves the right to make changes to the machine after this manual release date that may not
immediately appear in this manual.
Every effort is made to send out updates on a regular basis. If the machine in question was built after
the release date of this manual and there is a discrepancy, call Tigercat service department. The release

S.A.E. STANDARDS
ROLL-OVER PROTECTION STRUCTURES (ROPS)
FALLING OBJECTS PROTECTION STRUCTURES (FOPS)
OPERATOR PROTECTION STRUCTURES (OPS)
* MODIFICATIONS AND REPAIRS:
The integrity of the ROPS, FOPS, OPS structure and its continued ability to provide the level of protection
it was designed for could be seriously affected by any modifications to the structure, its mounting or to the
chassis to which it is attached.
Tigercat emphasizes that the certification of approval of the ROPS, FOPS, OPS structure will become
void if any such modifications take place.
Tigercat may officially grant approval for modifications only by:
i) Written approval of repairs or modifications signed by the Tigercat Engineering Manager; or
ii) Approved modifications officially released by Tigercat.
Both of the above are provided that the work is carried out in the factory approved manner.
Unauthorized modifications and/or repairs made or contributed to by a customer or a Tigercat distributor
may result in creating a dangerous situation and therefore the customer or Tigercat distributor will be
considered to have assumed the risk involved or be negligent in creating this situation.
Tigercat will not be held responsible for situations arising from having created unauthorized
modifications/changes to the structure.
Operator's cabs are designed to ROPS, FOPS, OPS standards so that they will withstand force and
absorb energy during a roll-over (ROPS), when resisting the impact of a falling object (FOPS) and
minimize the possibility of operator injury from penetrating objects (OPS). When a permanent deflection
of the structure occurs, the structure can no longer provide the original designed level of protection and
should be replaced. Attempts to straighten the structure, particularly by the application of heat, can
reduce still further the structures remaining capability to protect.
The mounting and the frame or chassis to which the cab is attached is considered an integral part of the
ROPS, FOPS, OPS and is included in the design, test and certification of the product.
Contact the Tigercat Service department before attempting any modifications or repair to roll-over
protective structures.

of various options may have on your machine.

authorization by Tigercat as stated above, Tigercat will take whatever action is appropriate to protect its
